Sunspot Drawings Photosphere Observed from Sacramento Peak Solar Observatory |
|
The photosphere of the Sun has a temperature of around 6, 000 degrees K and is the
region in which sunspot activity is located. Sunspots appear dark against the surface
of the sun due to the sunspots lower temperatures. Sunspots are solar active regions
having strong magnetic fields and propensity for erupting in the form of solar flares.
They typically form near the solar equator. The National Solar Observatory (NSO) has
provided the National Geophysical Data Center (NGDC) with a full set of daily solar
sunspot drawings prepared by the Sacramento Peak (Sac Peak) Solar Observatory. |
